What is the risk of missing orbital cellulitis in children?

Area of Science:

• Ophthalmology
• Pediatric Emergency Medicine
• Infectious Diseases

Background:

• Distinguishing preseptal cellulitis from orbital cellulitis in children presents diagnostic challenges.
• Periorbital infections frequently lead to hospital admission for intravenous antibiotic treatment.
• The study addresses the critical need to understand the risks associated with missed orbital cellulitis diagnoses.

Purpose of the Study:

• To investigate the incidence and risk factors of misdiagnosing orbital cellulitis in pediatric patients presenting with preseptal cellulitis.
• To evaluate the clinical outcomes for pediatric patients with initially missed orbital cellulitis.

Main Methods:

• A prospective cohort study involving 216 children aged 3 months to 18 years diagnosed with preseptal cellulitis over a 5-year period.
• Prospective data collection encompassed demographics, clinical presentations, and patient outcomes.
• Treatment strategies, including oral versus intravenous antibiotics, were documented.

Main Results:

• Out of 216 children with preseptal cellulitis, 5 (2%) were later diagnosed with orbital cellulitis after hospitalization.
• These 5 cases involved either very young infants with challenging eye examinations or children presenting with headache or vomiting.
• Treatment varied, with 35% receiving oral antibiotics and 65% receiving intravenous antibiotics.

Conclusions:

• The risk of missing orbital cellulitis in children initially diagnosed with preseptal cellulitis is low.
• Clinical indicators such as young infant age, difficult eye examinations, headache, or vomiting should heighten suspicion for orbital cellulitis.
